Toward-the attainment of, the primary objectreferred to above, the resent invent on contemplates various ancillary objectsfqf'inventions related to the constructionof certain 'meohw nisms of a typewriter as will. hereinafter be referred to in the body of the sPecIfication and be pointed out in.the appended claims. In the present application, I do not claim the particular construction of key lover or type bar actions which are herein shown and described since they constitute the subject matters ot' my copending applicat ons, Serial Numbers 128,248, filed October 28th, 1916, and 273,885, filed January 29th, 1919.

I Referring more particularly to the drawings, in Fig. 1, type bars 1 to 29 inclusive are operated by keys 1' to 29' inclusive. A spacing bar 30 which is pivotally connected at 31 to bar levers 33, is provided with lugs 32 which limit the spacing bar 30 in its downward movement relatively to bar levers '33 but permit said space bar to be folded into storage position shown in dotted lines in Fig. 1.5 in which position 1t does not extend beyond the front or the top limits of the main frame. When said space bar is in normal position shown in full lines, lugs 32 on the swinging portion engage the under edge of levers 33, thus limiting the downward displacement of space bar 30 relatively to and adapting space bar 30 and levers 33 to act as a rigid lever.

Pin 36 on which lever'35' is pivoted willtake the o'sition 61 anjdpin' 39 will be shifted to posilion .63. Pin 39 being attached to the auxiliary "frame '54, the-platen axis will be shifted'outwar'dto' 63, putting it in printing position for'the extreme end character of the'ty e bars. Upon removing the pressure on he shiftkey the parts return to fiositio'n. It W1 be note'dthat there'is an opening 64 through thelioor of the upper member of the rhain frame directly overpin 37, said in connecting shiftlever 35" with link 35.

it is therefore evident that as soon as shiftkey '40 is depressed a slight amount, causing rotker arm 45 to turn slightly toward the rear, the rear end of'lever '35 at pin 37 starts on its mov'ement'backward under the 65 solid part of the upper part of main frame toi'the rearzofqpenin 64;.it is'therefore impossible to move shift-key 35" downward rafter shift key 40' has begun to move downward, as the =rea-r endiof lever 35 is out of coincidence with opening 64.

When shift key 35 is pressed slightly downward it starts through opening 64 'thenefore'lhaking-ltimpossible to move shift key 40 downward as any backward movement ofthe. rear end oflever35' is prevented 'byits coming in contact with the back of opening 64;

It is therefore clear that two sets of shift levers are interlocked against each other so "that it is impossible to put either into action'after the other'hasstarted to act, until the lever acted upon has returned to itsnor- 'mal'position. It is also clear that'the shift "leversysterns are positively locked a ainst Ataickspace ke may be. placed at 34 i -with afle ver eitend ng backward andengagroller arm 1340f .a lever suitably enfga ing the esca' ement' mechanism.

znother app icatio'n of my improvement isilltistrated'by-Figs. I3 and 14in which the main featu'res'are substantially the same as Iin the embodiment before described. Acco'rdin to',this embodiment, the type bar pivot 'aring block 52 and the pivot pin "53 are :placed lower down in the machine thus sh fting the point of strike on the platen somewhat forward of the top. 'The lever action is illustrated by key 15 the stem of which is hung upon two parallel members,'link 140 and one arm of lever 141, the other end of the lever being connected ,at 66. to a link connecting with the type bar at 67. A second arm oflever 141 extends downward and to this is connected :1 pusher rod 142 which is guided in a slot in member 143. When key 15' is pressed down to dotted position 15 the several connected parts take the. positions indicated in dotted outline with the type in striking position on the platen and the universal bar 69 moved to the dotted position through the action of the pusher 1'42. Carriage roller rests upon a round rod trackinplace of the flat track of the preceding machine. The case shift of platen is diagonal'from 62 to 63' to correspond to the angle of the type bar when in striking posi tion 5315. Theauxiliary frame is hung on two'pairs of links73 and 73 the pair 73 takingv the place ofthe bent shaft 78' of the previous case, so far as the hanging of the auxiliary frame is concerned. the second function of shaft 78, the maintainingof the links 73 on the opposite sides of the machine inparallel with each other, is in this case performed by a separate shaft 78 having a lever 13'. on each end connected by two links 139 to the two links 73'. Shaft 78' is operated by suitable case shift mechanism, the extreme throw in each direction being regulated by adjust- A able 'stops 138 which are here shown as eccentrics clamped to the main frame by screws."and which limitthe movement of a levera'rm connected with lever 137.

' i In Figures 1to 14 inclusive, my invention v is exemplified in a double shift type of m a '10 chime in which there are three characters on 'each'type'bar, and. only three tiers of keys.

section Fig. 15 on the other hand exemplifiesmy invention in an adaptation to a typew'riterwitha standard four tier key- 15 board and only two characters oneach type bar, requiring-but a single case shift.

The typewriter keyboard as standardized by years .of use takes up, including the space I bar and dip'of sam e, a space about two and a) one-.half' i'iiche's high and about eight and one half inches long'for thelfour'tier, sinle shift keyboard and'a slightly less height I three tier, fdouble shift keyboard.

According'to my invention the'desi "'"and rh a r sic a cx i t ad ar k ractigall'y within th s standard keyboard he'ightand length while the d dimension a, from the front offthekeyboar totheback ofth e'platen carriage, reduced to av mini- 'The,smalles t dimension ,of lthe bank of type bars,as ordil'larilfdisposed is considerably in excess of the height of the standard I 95 keyboard.

R fer i tofFi', 5,108, 109,110 and 111 represent a plane cutting the point of strike an d pivots of a bank of typeb'ars which are ,piyoted on the curved rod-109,- 110. As or- 40 dinarily placed, the ebars are normally perpendicular to this p ane. Only the two endbars at 109 and the two center bars at 110 are shown in this diagram, the others being represented by dots'along' the pivot line.

Fig; 6 shows the ty e bars at 109 and 110 standing perpendicu ar to the plane 108, 109,

110. From Fig. 6 it is obvious that theleast height of a rectangular space which includes a bank of typ bars as well as their striking 5 points, is represented by the dotted line 108,

118-119, rectangle being 118-108. The

perpendicular type bars are-arranged to conform to the surface of a cylinder whose axis is perpendicular to the plane 108, 109 and '55 110 and passed through the striking point If in normal position the type bars are dropped back to an angle ofabout 120 degrees from the plane 108, 109, 110 1.11 as shown by the dotted outlines of the bars at 112, 113 the bank of bars will lie in the surface of a cone Whose apex lies within the perpendicular to the plane 108, 109, 110, 111.

, at the point of strike 108. This disposition 5 of the type bars reduces the height of the from 109 to'108;it'is therefore obvious-that reducing the space which they occupy,

minimum rectangle to that indicated by the dotted line 108-120-121.

If now, the type bars in normal position are made to assume positions 115, 116, 117, such positions being 180 degrees from the strikin point, the faces of the type will lie in t e plane 108, 109, 110, 111 and the depth of the space forcontaining the type bars will be reduced to the distance 122-123 which is the dimension across the pivot end of the 'typebar. The length of this rectangular space will then be the distance from point 108 to the line 122-123.

It is further obvious that as the normal position of the type bars is thrown back to a greater angle the space between the type heads is opened up,'the type at'115 being twice as far apart, center to center, as at 109, as is seen by comparing the type heads at 115 with those of Fig. 7 which isjan elevation of bars 109 as viewed'ffr'om the axis perpendicular to 108. In passing from normal' to striking position the type Heads travel just twice as far from 115 to 108215 '90 typebars 115 may be shortened to iust'oriehalf' their 'l'en'gth and "still have the "same spreadbetween type and the same distance of travel for a hammer blow as has type bar 109. Since these type bars will be just half as long, the rectangular space required therefor will be from 108 to 110 instead of from 122108 (see Fig. 6) which is quite a reduction in space as compared :to the space occupied by the 109, or 9.0 degree bank of bars.

Likewise type bars 112 acting through 120 clen'rees angle may be considerably shortened with respect to the 109" bars, thus greatly This angle, 120 degrees, I find to' beabout the least that will permit the bank of type bars to be kept within the confines of the height of the double shift keyboard. Figs.

13 and 14 illustrate how type bars operat- 1'10 ing through about 120 degrees may be located in a machine. It will be noted that the highest corner of the extreme outside type block 29 is just barely within the horizontal. top line of the main frame which is 115 on a level with the top of the top key 17' while the pivot end of the middle bar at 53 barely clears the bottom floor of the main frame as the bar swings to' the striking position indicated by the dotted line of the bar 15. The top of platen 56 is also barely below the horizontal line coincident with the top of key 17.

In the preferred application of my invention, however, I operate the type bars through an angle of about 180 degrees and I have devised a lever motion whereby I am enabled, by connecting the key lever by a single link to the type bar. to swingthe type bar through this great angle with an main frame saidlin s p v t l ne d o th iai a y cave .plate 8 the balls out:

preferred embodimentof my invention to the ,doubleshift typeiof machine is illustrated in Fi res 1, 2, 3, 4', 5,9, 10, 11 and 12.

A doglQO is 10 also carried by theiro cking bar 97' indengages another tooth of wheel 80. When bar 97 is in normal position as shown'in Fig. 12, jaws 99 are forward of and out of engagement with the teammate escapement wheel. 'Pawl 100 is on the contrary in full engagement with a wheel tooth. In operating the escapement, bar 97 is swung on its pivots to throw the jaws 99 backward toward thelplaten position to-such anextent as to fully engage a toothof the escapement wheel. At the same time pawl 100.is car ried backward to an extend which entirely disengages it from the escapementwheel. As soon as dog 100 is freed from engagement with the wheel it swings downward on its pivotito the extent of one tooths space so that when bar 97 returns to its normal posi- .tion it enters the space next below the one it had just left. As soonas jaw 99 releases its tooth the escapement wheel advances one tooth space which is the limit of swing provided for in the vibrating pawl 100. Bar 97 is vibrated through the action of a suitable universal bar upon the rollers 98 pivoted to the forward extended arms 97. To these forwardly extended arms are also pivoted pawls 101 which engage ratchet wheels attached to worm shafts 102. These worms operate worm wheels attached to ribbon spools 106 to properly feed the ribbon. The ribbon spools are carried by shafts 107 mounted in the vertical end walls of auxiliary frame 54 and brackets 128 attached to same. By thus mounting the spools on edge on horizontal axes I am able to use standard spools with ribbons of standard length instead of the much shorter ribbons used on some portable machinesi The ribbon, 48 Fi'gfl, passes from the ribbon Spools over the ribbon shelves 49' and through diagonal slots in the ribbon guides 49 and then across from one guide to the'other through the slot in the end of the vibrating arm 47. Clearance slots 165 are provided in main frame for ribbon spool shafts 107 (see Figs. 2 and 10). The above described escapement mechanism constitutes the subject matter of a separate'application, Serial No. 169,676, filed Mai? e 19th, 1917.,

ferring to Figsi, 3, 11 and 15, key levers 1 to 29' are pivoted to'wall 51' of upper member 51 of main frame by means of'piv'ot pins which are clamped to 'wall 51' b mea s of blocks r34 and sere'ws tappe into same. keyleverfis'pro': 'vided with'a pair of lugs pivoted on a pin 65. Wall 51' isasisction of'a hollowcone from'which the type'bars radiate: 'In Fig, 11 pairs of clearance openings 65' are shown for "the pivot lugs of key, evers'. Only a few of the29 pairs of openings 65' "which cover the "greater'part of wall 51are shown in the figure. The full lines show the key levers in'theinnormal position; .Iiever 15' is pivoted to wall 51 at 65. The inner end of said lever is pivoted ,at 66 (see Fig.3) to a short curved-.linkwhose other end is pivoted at 67 to type bar 15. Type bar 15 restsnormall upon cushion 125' carried by shelf 124. T e short link is held in normal position, preferably against the bottom of the slot in the'type bar pivot block 52, by a ,sprin attached to sprin hook 68 and being t us held it in 5111115101115 the type bar and key lever to which it is attached in normal position. When the key 15' is depressed to the position shown by dotted lines the short link takes the dotted line position 66-67 and the type bar takes the. striking positionshown by the dotted line 15 above the platen. The type bars are guided to exact striking position by guide 59, bars 10 to 20 falling into the center slot, 1 to 9 in slot 58 and 21 to 29 into slot 57. Sprin hook 68 takes the dotted position 68. aid spring hook is provided with a curved depending arm which operates in a V groove in the universal bar 69 for raising the latter to dotted line position. A shelf 70 (see Fig. 3) suspended from the universal bar 69 by two legs 69, engages the under side of two rollers 98 (see Fig. 12), raising them and thus rocking bar 97 to perform its several functions. The uni versal bar is guided at each end by two links 71, one end of each of said links being pivoted to a leg 69' of the universal bar and the other end to one of the brackets or standards 72 hereinbefore referred to. From space bar 30'there extends inward at each end a lever 33 Fig. 15 pivoted by pin 136 on bottom plate 50 and having its "inner end 33' in engagement with one "of said legs carried by the universal ba'r'so that w en said space bar is depressed the universal bar will be elevated to operate the rocking bar 97 (see Fig. 12) and thereby cause said bar to perform its functions in the'same manner as when a type key has been operated.

Fig. 15 illustrates theapplication of my invention to a machine having a. complete standard keyboard with four rows'of keys and oxiIya single case shift for type bars bearin only two characters ear-h. The auxil iary mine is here shown mo'vaibly mount ed in the main frame by means of wheels instead of parallel links, wheel 144 being axledon the auxiliar. frame and rollin .on the'bottom" late oft e mainframe. 1 heel 145 is ax'lfed on the main frame and is eng'aged' by a'flat surface 146 attached to the auxiliary frame. The weight of the carriage, p ten 'and other parts making the weight of the auxiliar' frame to the rear of roller 144 heavier than the part'toward the .front of the machine, the pressure is upward against wheel 145. Wheels 144 anil 145 are 'du heated on the other side of the frames. wo case shift levers 35 are attached rigidly to shaft 148, one at each end, and short arms of the levers extending upward are pivoted to the main frame at 149 at each side. A link 14.7 at each side of the machine connects shaft 148 with the auxiliary frame at 150. When key 35' in depressed to dotted position its lever swings on screws 149, bringing lever, shaft and link to the position shown in dotted line shifting the center of the platen to 63. Other parts of this machine are p111 tically the same as the one first described and require no further explanation.

' When space bar 30 and paper rack 93 are folded to their dotted positions n.) part ofthe machine extends outside of the rec tangle indicated by the dotted lines 16 161, 162, 163 of Figs. 2, 13 and 15. The feet of these machines consist of cushions 151 held by sockets 152 screwed to the bottom of the frame. By using a collapsible or folding foot the height of the machine may be still further reduced.

Figs. 16 and 17 show a foldin foot, 50 being portion of the floor plate 0 the main frame. The socket 152 which holds pad 151 instead of being secured directly to 50 is attached to a separate member 153 which is provided with two lugs 154. These lugs are. pivoted on pin 155 which" is clamped=by member 156 to the floor plate 50.
